The French Bulldog, like many other companion dog breeds, requires close contact with humans. As a result, they should not be left alone for more than a few hours because these dogs suffer from separation anxiety if they are alone for too long. This is especially important when French Bulldogs are young, but this issue remains a concern into adulthood. Being alone for too long can cause a French Bulldog to behave in a destructive manner, which can include chewing on household items or furniture or even going to the bathroom in the house.
They have fairly minimal exercise needs, but do require at least daily short walks. The French Bulldog is sometimes called "Frog dog" or a "Clown dog". Frog dog is in reference to the unique way they sit with hind legs spread out. Clown dog is because they are known to be fun loving vivacious "clowns of the dog world". Their calm nature makes them an excellent choice for apartment dwellers, as does their sensible attitude towards barking.
Their bulk and their compromised breathing system makes it impossible for them to regulate their temperature efficiently. The French bulldog has only a single short coat. What this all means for the dog is that it becomes cold very easily. Also, they will very likely need to have some extra covering inside during the winter in particularly cold areas. These dogs need warm clothing when out in cold weather. Precautions must be taken when exercising during hot or humid weather, as they are prone to heat stroke. It is also recommended that French Bulldogs who live indoors have access to air conditioning to regulate their temperature, provided the air conditioning is not set too low.
A UK breed survey report on 71 dog deaths put the average lifespan of French Bulldogs at 8 to 10 years, while the UK breed club suggests an average of 12 to 14 years. The AKC lists that the French Bulldog breed has a lifespan of 11 to 13 years.
As a result of the compacted airway and the bulk of the French bulldog, they have an inability to effectively regulate their body temperature. While a regular canine may suffer to some degree from the heat, to a Frenchie it may be lethal. It is imperative that they be protected from temperature extremes at all times, and that they always have access to fresh water and shade. As they are a brachycephalic breed (see Brachycephalic syndrome), French Bulldogs are banned by several commercial airlines due to the numbers that have died while in the air. This is because dogs with snub noses find it difficult to breathe when they are hot and stressed out. The cargo space in an aircraft can rise as high as 30 °C (86 °F) when waiting on the runway.
